CAR-COUPLING.

SPECIFICATION formingpart of Letters Patent No. 269,857, dated January2, 1883.

Application filed October 23, 1882.

T 0 all whom it may concern:

Be it known that I, JOHN W. HOLLIS, a citizen of the United States,residing at Oincinnati, in the county of Hamilton and State of Ohio,have invented certain new and useful Improvements in Gar-Couplings, ofwhich the following is a specification.

In my improved car-coupling the draw-head tapers toward its outer end,and is provided with a mouth extending from side to side of the head andrunning about half the length of the same, a horizontal shaft or boltbeing passed through the head in the rear of the month, which shaftcarries the link. This link is made in the shape of a converging loop,bail, or shackle, with an eye at each end, which eyes are traversed bythe above-described bolt, while the bend of the link receives all thestrain of the coupling-pin ofthe adjacent drawhead, as hereinafter morefully described, and pointed out in the claims.-

In the annexed drawings, Figure l is a perspective view of my improvedcar-coupling, the converging link being shown in its normal or pendentposition. Fig. 2 is a plan on a reduced scale, showing the link broughtto a horizontal position with one of the lifters and its free endinserted in an ordinary draw-head.

The inner portion, A, of the draw-head is about square in transversesection, and is bored horizontally to receive a short shaft or bolt, B,having at one end a head, 0, and at its other end a washer or nut, D.Suspended from this bolt, and adapted to swing freely thereon, is thelink E, having two eyes, F F. This link, instead of running parallel iththe sides of the draw-head A, converges toward its center or bend G,thereby affording unusual strength at the part of said link where itpulls against the coupling-pin n of the opposing head N. The outer endof head A has a tapering portion, a, through which passes an ordinarycoupling-pin, H. Furthermore, a mouth,

I, is provided, running completely across from side to side of the head,and extending back into the square portion Aofthe same.

Projecting from the end of the car are bearings J for a rockshat't, K,having at its inner end a crank, L, of such a length as to engage underthe link E when occasion requires.

(No model.)

I The outer end of this rock-shaft has a handle or lever, M. Located onthe opposite side of the draw-head, in bearings J, is another rockshaft,K, having a crank, L, and lever M, which latter may be provided with ahorizontal extension, m.

Nvis an ordinary draw-head, having a oustomary coupling-pin, n.

By referring to Fig. 1 it will be seen that the link E F FG,when in itsnormal position, swings freely from the bolt B, and leaves the top ofthe draw-head perfectly free and unob str ucted. As soon however, as itis desired to connect with another car, the coupler has only to graspeither of the levers M or M mand so turn the shafts K or K as to causethecranks L or L to swing upwardly and lift thelink far enough to guideit into the mouth of the opposite draw-head, which entrance is readilyeffected on account of the con verging shape of said link. Now, if thedraw-head were of the same width from end to end as the portion A, it isevident the converging link could not be raised far enough to engagewith the coupling pin of the other car; but by tapering or chamferingoff the sides of said head, as at c, ample clearance is afforded forsuch a movement of the link.

When the cars are coupled it is apparent all the wear and tear of thepin a is sustained by the bend G of the link, and, as this bend is asolid or unwelded bar, there is no possibility of it breaking or pullingapart. Furthermore, it is apparent that the pull against the head A isaccomplished by theeyes F F, that embrace the bolt B, thereby afi'ordinga twofold hold of the link, and in case one of said eyes should breakthe other would still be sufficient to draw an ordinary train.

Another advantage of my invention is seen in the arrangement of thelilting appliances K L M, which, being attached to the end of the car,are not injured in case the draw-head should be detachedeitheraccidentallyorotherwise. Finally, the chamt'ered portion of thedraw-head may be confined to that part below the mouth I, and the endabove said mouth IOO 1.
